Hej Janne,
nice to see you join in.

The link you provided is a nice tool and sure sounds better than I'm able to explain by writing.
But that said, it may be some local variations depending of where we are around the Scandinavian
countries due to local native tongue.
Swedish in general are more "melodic" than Norwegian that is more "stright forward" sort of speak.
Also if you listen to the way they sing in YouTube clip, and the word spoken in the spoken clip
it's a difference even if both are Swedish.

Skål, og ha en trivelig Jul og et Godt Nytt År!
